.IMPROVIEMENT IN JOINTED PIPE-CONNECTIONS.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom it 'may concern.:

Beit known that I, Hman Bunn, of Norwalk, in

and State of Ohio, have invented certain new and useful Improvements in Water-Tank Pipe-Joint for Railroads; and I do hereby declare that the following is a full and complete description'of the same, reference being had to the/ac coinpanying drawings, making part ofthis specification, in which- Figure 1 is a side view of the pipe and joint.

Figure 2, a view ofthe top.

Like letters of reference referto like partsin the diierent'views.

This invention relates to a jointed connecting-pipe, whereby the tender of a locomotive is supplied with water from the reservoir, the joint in the pipe being such, that said pipe is readilyand easily adjusted to the position and height of the tender, as hereinafter more fully described. l

The comlucting-pipe, or conductor referred to, is constructed in two sections, A B, fig. l, section A being of larger diameter' than B, and into which the end of B is screwed, as indicated by the dotted-line a.

The end or head C, introduced into section A, is provided with an elastic packing, a, fig. 2, whereby the head or end'f the pipe is made water-.tight in its connection with the pipe A, and which also allows oi' its being` moved about therein for the purpose of adjusting the pipe tothe tank of the tender.

The two sections of pipe are secured to cach other by means of the curved standard D. The lower end of said standard is fitted in the boss E, in which it turns, or it can be secured tightly therein by a set-screw iu the s ide of the boss.

The upper end of the standard is connected, by a hinged joint, to a stem, F, loosely fitted in a stay, G, in which it turns, and is prevented from coming out byv a nut, H, screwed to the stem below the stay.

Having thus described the connection of the pipe or conductor, the practica-l operation of the same is asv follows, viz: I

Section B is screwed in the side of the reservoir, so that it may project forward from the side ofthe build- When n'ot in practical use, section A is detached and 'swung around at right angles to section B, asv shown in iig. 2, aga-inst the side of the house.

When it is required to use the conductor, section A isswung around from its right-angle position to section B, until the two sections are in line with cach other. Now, on depressing the'extreme end .of A, the head or end C ot' section B will enter the pipe A, as indicated by the dotted line a, iig. 1, in which it will be seen that the pipe A is deflected downward from a horizontal line, and which, at the same time, may be turned laterally more or less, as the position of the tender on theltrack may require, or it may be elevated or depressed, as the height of the tender may render necessary.

rlhis elevation and depression of section A are attained by the jointed connection of the curved standard to the. stem F, and the lateral movement to thc freedom allowed the stein in the stay; hence, by this combined movement of the section, it will be obvious that the pipe can be easily adjust-ed to tenders of different heights, which have an average difference of only a few inches; der not stand exactly in range with the dischargingpipe B, the section A can be turned to either direction, so as to make the proper connection with the tender for receiving water.

1t will be observed that the section A is slightly tapering, it being large at the'end, receiving the end oi' section B, the purpose of which is tocause the packing c to lit closely, on the introduction of the-head, and thereby prevent leakage.

It will also bo seen that section A is smaller at or near the head than it is at the 'opposite end. By this means, greater freedom is obtained to the pipe in its lateral movement. Therefore, the engine can be supplied with water, though the tender may not be stopped directly opposite the comlueting-pipe.

By the use of this jointed water-pipe, trouble and delay in the movement of the train are avoided, but which are unavoidable in supplying the tender with water in the ordinary way, as it is necessary to stop the engine at the exactjoint to bring the conductingpipe so as to make the connection; and should a canvas or other flexible pipe he used, in order to adapt the pipe to the height of the tender and its position on the track, such pipe is soon worn ont, or becomes injured, leaky, and worthless, which, however, cannot be the result with. the pipe herein described. It being made wholly of metal, is, therefore, strong and durable, and, being provided with the flexible joint, is easily and readily adjusted t-o the tender.

In orderI to prevent section A fronr being swung around too far, and thereby cause unnecessary strain to be exerted upon the joint, a stop, c, fig. 2, is arranged on the stay, immediately back of the stem, against which it will strike on coming around, thereby restraining it from going too far.

Each section of tl1e,pipe(as above said) is made tapering, but which, however, may be made straight, if so desired.

. What I claim as my improvement, and desire to secure by Letters Patent, is`

The ,sections of pipe A B, standard D, and swivelled or hinged stem F, as arranged and combined, to operate conjointly in the manner substantially as described, and for the purpose set forth.
